Abstract

This invention relates to a self-expanding pre-configured compressible transcatheter prosthetic cardiovascular valve that comprises atrial thrombogenic sealing pocket cover mounted on a self-expanding inner wire frame having a leaflet structure comprised of articulating leaflets that define a valve function, said inner wire frame is disposed within a self-expanding annular tissue-covered outer wire frame, said outer wire frame having an articulating collar, forming a multi-component prosthetic valve assembly for anchoring within the mitral valve or triscuspid valve of the heart, and methods for deploying such a valve for treatment of a patient in need thereof.

Claims

1. A self-expanding pre-configured compressible transcatheter prosthetic cardiovascular valve that comprises an atrial thrombogenic sealing pocket cover disposed between a self-expanding inner wire frame and a self-expanding annular tissue-covered outer wire frame, said inner wire frame having articulating tissue leaflets that define a valve function, said inner wire frame is disposed within the outer wire frame, said outer wire frame having an articulating circumferential collar, forming a multi-component prosthetic valve assembly for anchoring within the mitral valve or triscuspid valve of the heart.

2. The valve of claim 1, further comprising a tether structure connected to the inner wire frame or the outer wire frame.

3. The valve of claim 1, further comprising a tether structure connected at a distal end to the inner wire frame or the outer wire frame and an epicardial pad connected to the proximal end of the tether structure.

4. The valve of claim 1, wherein the inner wire frame and the outer wire frame are made of a self-expanding compressible nickel-titanium biocompatible alloy.

5. The valve of claim 1, further comprising wherein the tissue is derived from adult, 90-day old, or 30 day old, bovine, ovine, equine or porcine pericardium, or from animal small intestine submucosa.

6. The valve of claim 1, further comprising wherein the cover or tissue is synthetic material and is selected from the group consisting of polyester, polyurethane, and polytetrafluoroethylene.

7. The valve of claim 1, wherein the cover or tissue is stabilized tissue or synthetic material is treated with anticoagulant.

8. The valve of claim 1, further comprising one or more standard anchoring elements, including but not limited to barbs, pins, and/or hooks, or combinations thereof to mount the valve within the cardiovascular valve annulus.

9. A method of treating a disease or disorder of a heart valve in a patient, which comprises the step of surgically deploying the prosthetic heart valve according to claim 1 into the native annulus of the heart valve of the patient.

10. The method of claim 9, wherein the native annulus is the mitral valve annulus or the tricuspid valve annulus.

11. The method of claim 9, wherein the prosthetic heart valve is deployed by directly accessing the heart through the intercostal space, using an apical approach to enter the ventricle, and deploying the prosthetic heart valve into the native annulus using a catheter delivery system.

12. The method of claim 9, wherein the prosthetic heart valve is deployed by directly accessing the heart through a thoracotomy, sternotomy, or minimally-invasive thoracic, thorascopic, or trans-diaphragmatic approach to enter the ventricle.

13. The method of claim 9, wherein the prosthetic heart valve is deployed by directly accessing the heart through the intercostal space, using an approach through the lateral ventricular wall to enter the left ventricle.

14. The method of claim 9, wherein the prosthetic heart valve is deployed by accessing the left atrium of the heart using a transvenous atrial septostomy approach.

15. The method of claim 9, wherein the prosthetic heart valve is deployed by accessing the left ventricle of the heart using a transarterial retrograde aortic valve approach.

16. The method of claim 9, wherein the prosthetic heart valve is deployed by accessing the left ventricle of the heart using a transvenous ventricular septostomy approach.

17. The method of any of claims 9-16, further comprising tethering the prosthetic heart valve to tissue within the left ventricle.

18. The method of any of claim 9-16, wherein the prosthetic heart valve is tethered to the apex of the ventricle using an epicardial tether securing device.
